JOHN B. BAXTER, 0F WATERVLIET, NEW YORK, ASSIGNOR T0 COVERT MANUFAC-TURING COMPANY, OF WATERVLIET, NEW YORK, A CORPORATION OF NEW YORK.

COMBINED BREAST-STRAP SLIDE AND ATTACHING MEANS THEREFOR.

Application filed December 12, 1916.

To all whom it may concern:

Be it known that I, JOHN B. BAXTER, a citizen of the United States,residing at lVatervliet, in the county of Albany and State of New York,have invented certain new and useful Improvements in CombinedBreast-Strap Slides and Attaching Means Therefor, of which the followingis a sp'ecification, reference being had therein to the accompanyingdrawing. I

This invention relates to combined breast strap slides and attachingmeans therefor.

In my copending application filed concurrently herewith, I haveillustrated and described a novel and improved combination article ofthe character just referred to, which includes a breast strap slideproper and a pivotally connected snap hook or the like, and having amongits objects increased strength and durability, and to overcome to anappreciable extent the usual incident wear upon the edges of the strapin the movement of the latter relative to the slide.

It isone of the objects of the present invention to incorporate in adevice of the general character illustrated and described in mycopending application, means whereby to further reduce the friction inthe movement of the strap, thereby facilitating the operation andincreasing the life of the strap.

In carrying out the invention it is proposed to interpose in the bodypart of the breast strap slide, a roller or anti-friction bearing forthe strap, with the IIICIdBIIt ease in operation of the latter, theother assoclated parts of the device being constructed and arranged toprevent undue wear upon the sides of the strap in the free movement ofthe latter on the roller.

Another feature of the invention resides in a novel construction ofslide having a strap engaging anti-friction bearing, of means forpivotally supporting the hook or other attaching device to the slide,whereby in the relative swinging movement of the hook and slide, theslide will constitute a guide and reinforcement for the hook, and meansfor preventing lateral play of the hook and undue strains upon the hookand pivotal supporting means therefor.

More particularly, the invention includes in combination with a breaststrap slide having a strap engaging roller bearing, of

Specification of Letters Iatent.

Serial No. 136,564.

a hook or other supporting medium having separated arm extensionspivotally mounted upon the body part of the slide whereby to constituteend abutments for the roller and edge abutments for the strap, thevarious parts of the device being constructed and arranged with a viewto neatness, simplicity, ease in operation, increased strength, anddurability.

Other and further improvements and novel details in the construction andarrangement of the various parts of the device will be readilyappreciated from the description to follow and from an inspection of theaccompanying drawings, which form a part hereof, and wherein isdisclosed for the purpose of illustration a convenient embodiment of theinvention, which has proven highly satisfactory in use.

In the drawings Figure 1 is a'perspective view of the combinationdevice.

Fig. 2 is a top plan view of the breast strap slide and the partspositioned thereon.

Fig. 3 is a similar view of the breast strap slide with the associatedparts removed.

Fig. 4 is a longitudinal sectional view of the slide and engaging end ofthe attaching device.

Fig. 5 is a transverse section, parts being broken away.

Referring to the drawings in detail, it will be noted that likereference numerals refer to corresponding parts throughout the severalviews, in which 1 designates opposed sides of the body portion of thebreast strap slide proper, said sides connecting with curved portions 2separated from one another by a roller receiving space 3. Integral withthe curved bottom portions 2 and the sides 1 of the slide are end loopmembers comprising end bars 4E and side bars 5. The sides 1 of the bodyportion of the breast strap slide, as well as the bottom portions 2thereof,- project outwardly beyond the sides 5 of the loop extensions,and in said extended portions of said parts there is provided anelongated slot or recess '6.

Adapted to be pivotally mounted upon the breast strap slide as justdescribed is a suitable hook or other attaching means. In theillustrative embodiment of the invention, this attaching means takes theform of a snap hook comprising a hook portion 7 a A suitable rollerbearing 13 is adapted to be positioned in the space 3 of the breaststrap slide, and conveniently a common means of support for the hook androller is provided, the same in the embodiment of the inventionillustrated, taking the form of a rivet or bolt 1% having headed ends toengage the outer surface of the sides 1 of the breast strap slide andloosely projecting through the apertures 11 of the hook arms 9 andthrough a central aperture extending through the roller 13. It will beobserved that-the engaging ends 10 of the hook arms 9 are positioned inthe slotted portions 6 adjacent the sides of the body portion of thebreast strap slide, and that the swinging movement of the hook islimited by the ter minal walls of said slots which walls project beyondthe edges of the curved portions 2, whereby to provide abuttingshoulders to engage the inner surface of the arms 9 of the hook, whenthe hook has been moved to its limit in either direction.

The opposite arms 9 of the hook when in position on'the breast strapslide constitute end abutments for the roller 13, and the arms 9 will bebacked up by, and therefore reinforced on opposite sides by the rollerand the sides 1 of the body portion of the slide.

It will also be observed that because of the positioning of the arms 9in the slots 6 in the lateral extensions of the body part, the arms 9will be in substantial alinement with the side arms of the loops 5,whereby the strap will be effectively guided at its edges by the sidearms 5 of the loop members and the side arms 9 of the hook, and withoutany appreciable wear or friction, and in this con nection it will benoted that the arms r and 5 of the upwardly curved looped portions arerelatively wide and inclined as illustrated whereby to provide extendedbearing surfaces for the strap.

In operation, the breast strap; conveniently of substantially the samewidth as the roller, is adapted to be inserted through the loop portionswith the upper surface of the strap in contact with the under surface ofthe curved portions 2 of the slide and the underv surface of the roller,whereas the pivotally mounted snap hook is adapted to detachably engagethe neck yoke eye or other portion of the harness. The strap will freelymove on or over the roller, while its edges are guided by the sides 5 ofthe loop and the inner surfaces of the arms 9 of the hook. At the sametime, the hook may readily move about its pivotal support over the innersurface of the sides 1 of the body portion of the slide, and unduestrains on the arms 9, supporting rivet 14 and the like are overcome.WVhen the hook has reached its limit of movement in either direction,the arms 9 fit in the terminal portions of the slots 6 and anyunnecessary lateral strains in either direction of said arms is resistedby the shoulder portion 6 on the one side and the sides 1 on theopposite side.
